Locking system in ranked matches.

The locking system in ranked matches is inefficient, and nothing more than a troll makeshift system put into place which causes players with laggy clients to miss out and receive cooldowns.

Could nobody come up with a better system which allows players to ban characters first and then lock in the moment the character selection starts? Most of the time I have to wit 30 seconds after which the option to lock shows up on screen. This is plain inefficient and poorly built.
